I use this in my virtusertable:

foo at bar.com          error:nouser 550 No such user here

but you should be able to change the message half of that with no trouble.

That generates the following in my sendmail logs:

Mar 28 18:43:08 foo sendmail[11056]: 
k2T2g3Le011056: <nn at antimatter.net>... No such user here
Mar 28 18:43:11 foo sendmail[11056]: 
k2T2g3Le011056: lost input channel from 
200-100-163-150.dial-up.telesp.net.br [200.100.163.150] to MTA after rcpt
Mar 28 18:43:11 foo sendmail[11056]: 
k2T2g3Le011056: from=<ztomhmx at jtg.com>, size=0, 
class=0, nrcpts=0, proto=SMTP, daemon=MTA, 
relay=200-100-163-150.dial-up.telesp.net.br [200.100.163.150]
